Appendix
Differences between FT sensors:
V20 sensors
•
V20 sensors do not have configurable length averaging filters or the selective filter
(these options will not be available as configurable options)
•
V20 sensors have a heater setpoint range of 0-44°C
•
The latest software version is V3.6
V22 sensors
•
V20 sensors have a heater setpoint range of 0-55°C
•
The wind speed and direction averaging time can be modified on V22 sensors with
the latest software (0.2 to 12.8 seconds, in 0.2s increments)
•
Multiple software versions are available:
--Earlier sensors have a PCB with the latest software V5.4
--Later sensors have a new PCB with the latest software in the range V6.3-V6.5.1
•
V22 sensors with V6.4+ will have the ability to enable and configurable the Selective
Filter time period (a filter that rejects
“bad quality data” being output)
